Dipoto continues Mariners’ off-season overhaul

No major deals, but the Mariners added RHP Chris Heston from the Giants to end baseball’s winter meetings. Heston will compete for a back-of-the-rotation job in spring training.

Having consummated a major five-player trade, notably netting a new shortstop and leadoff hitter in Jean Segura, Mariners GM Jerry Dipoto did not figure to be particularly active at baseball’s annual Winter Meetings — and wasn’t. His most notable move during the three-day confab at Oxon Hill, MD., was the acquisition of RHP Chris Heston, a former starter expected to compete for a back-of-the rotation job.

Seattle will send San Francisco a player to be named later in order to acquire Heston, and designated for assignment INF/OF Richie Shaffer, acquired last month from Tampa Bay, to make room on the 40-man roster.

“Adding Chris is another move in our continuing effort to build a deep and flexible pitching staff,” said GM Jerry Dipoto. “His composure and solid feel to pitch has produced positive results at all levels throughout his career.”

Heston, 28, made San Francisco’s Opening Day roster last year and had four relief appearances. He spent most of the season with AAA Sacramento, where he went 2-9 with a 4.54 ERA in 15 games, including 14 starts. He also was on the 60-day disabled list with an oblique strain.

In parts of three MLB seasons, he is 13-12 with a 4.16 ERA. In 2015, he went 12-11 with a 3.95 ERA in 31 starts with San Francisco, including a no-hitter June 9 against the New York Mets. He was drafted by the Giants in the 12th round in 2009 out of East Carolina University (Greenville, NC).

The Mariners acquired Shaffer, 25, in a five-player trade with Tampa Bay Nov. 18. He appeared in 20 games over three stints with the Rays last year. Overall, he hit .250 at the MLB level after spending most of the year with AAA Durham in the International League.

The Mariners acquired two players on the final day of the meeting, selecting LHP Paul Paez from the Mets and OF Chuck Taylor from the Diamondbacks in the AAA phrase of the Rule 5 draft. Through the same process, the Mariners lost RHP Kevin Gadea to Tampa Bay and OF Austin Wilson to the St. Louis Cardinals.

Paez, 24, combined to go 4-1 with a 3.88 ERA in 55.2 innings with High-A St. Lucie and AAA Binghampton in the Mets organization. He was selected by New York in the 38th round of the 2013 draft out of Rio Hondo College (Whittier, CA).

Taylor, 23, last year hit .261 in 83 games with AA Mobile and A Visalia in the Diamondbacks organization. Taylor has played all three outfield positions in his three-year pro career. Arizona selected him in the fourth round of the 2012 draft.

Gadea, 22, combined for a record of 4-1 and 2.88 ERA in 15 games (eight starts) with AZL Mariners and A Clinton last season. Wilson, 24, hit .226 in 104 games with High-A Bakersfield.

Depoto’s moves represent only a fraction of his activity since the offsseason began Nov. 1.
